EVAN \V. JONES, OF PORTLAND, OREGON.

ROCK-YCIRIUSHER.

SPECIFICATION forming part of Letters Patent No, 329,048, dated October27, 1885.

Application filed March 12, 1885.

T0 aZZ whom it may concern:

Be it known that I, EVAN W. J oNEs, a citizen of the United States,residing at Portland, in the county of Multnomah and State of Oregon,have invented certain new and useful Improvements in Rock-Crushers, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompany ing drawings, forming part of thisspecification, in which Figure l is a perspective view of my improvedcrusher. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinalsectional view on the line 00 w of Fig. 2. Fig. 4 represents details ofthe main shaft E, and Fig. 5 represents views of the crushingdies.

Similar letters of reference indicate corresponding parts in the severalfigures.

My invention relates to a machine for crushing stone, coal, quartz, ironore, &c.; and it consists in the construction and combinations ofdevices, all of which I shall hereinafter fully describe andspecifically claim.

To enable others skilled in the art to make and use my invention, I willnow proceed to describe the exact manner in which I have carried it out.

In the said drawings, A represents the main bed-plate or frame, of anysuitable dimensions, design, and material, mounted upon a foundation ofstone or heavy timbers, as shown in Fig. 1.

Upon one end of the bed plate A, and formed integral therewith, is abearing, A, adapted to receive the bolt D, which has a rounded end andenables the lever B to have a rocking movement, the purpose of whichwill be hereinafter fully developed.

Journal-boxes A are also formed on the bed-plate at the end of themachine, opposite the bearing A, and in these boxes is mounted torevolve the main shaft E, upon one end of which is keyed a fly-wheel, W,and between the journal boxes A on the said shaft E is mounted thepulley P, to which power is ap plied to operate the machine.

The shaft E is formed with a wrist-pin, E, arranged so as not to beparallel with the main portion of the shaft, but in such manner that aline running through the center thereof when the shaft is in positionwill strike the center of the spherical-ended bolt D, be-

fore referred to, and as indicated by the dotted lines in Fig. 4. Theobject; of this construction is that the wrist-pin will always have atrue and solid bearing in the box in the end of the lever B, regardlessof the position of the main shaft. The spherical end of bolt D bearsagainst a box or-plate, F, in-

V manner as to permit of ready adjustment when the lower point of saiddie has become worn by its contact with the material to be crushed.

As before stated, B is a lever, by the operation of which the materialis crushed. This lever is of the construction shown in Figs. 1 and 2,and it is attached to the wrist-pin E" of the main shaft E byajournal-box, B, so that it may have a rocking movement during therevolution of the said shaft, which movement is permitted by the bolt Dengaging the opposite end of the lever and acting as a pivot oruniversal bearing upon which the said. lever turns.

Rollers H are mounted upon the crushing- .lever at its enlarged end andin a line transverse to the spherical end of bolt D. This is to preventthe lever from oscillating or rolling on the axis of the bolt, but atthe same time permit the lever to have free movement in all otherdirections.

Within dovetailed slots in the lever B are suitably securedverticallyarranged crushing-dies H and I, the latter having straightfaces while the former is of a configuration corresponding to that ofthe inner face of stationary die G, so that the material to be crushed,when placed in the space between dies G and H, is readily broken. As itapproaches the lowest point of these dies, it becomes thoroughlycrushed, owing to the fact of the die G being placed at an angle to theworking-face of movable die H, which brings these two dies closetogether at their lower or discharge ends. The space between these diesbeing regulated by raising or lowering the stationary die G in the blockA enables me to crush the material fine or coarse, as may be required.

The operation of my apparatus is as follows: Power is applied throughpulley P and crankshaft E to the contracted end of lever B, the otherend of said lever beingjournaled on the spherical end of pin D. One endof lever B being moved in a circle by the crank E, and the other endbeing held on the pin D, gives the lever wit-h the crushing-dies H and Isubstantially four distinct crushing movements during each revolution ofthe crank E, and

eat the same time that the pressure is on the rock the peculiar motionof the lever gives to the rock a wrenching or twisting strain,therebybreaking it much easier than could be done by direct pressure.

Having thus described my invention,what I claim asnew, and desire tosecure by Letters Patent, ,is

1. In a crushing-machine, the bed-plate A,

.a wrist-pin for giving a rocking movement to the lever B, substantiallyas and for the purpose specified.

' 3. In a crushing-machina'the combination, with the bed-plate A,provided with suitable bearing-blocks, the stationary die G, and theshaft E, provided with a wrist-pin,.and the pulley P, of the bolt D andthe crushing-lever provided with the rollers H and a verticalangular-faced die, substantially as herein described.
